Composite Sofa Leg

ABSTRACT

The utility model discloses a composite sofa leg, comprising a leg body and a shell made of plastic, wherein the upper end of the shell is open, the leg body is placed in the shell, and the top of the leg body is flush with or basically flush with the top of the shell. The shell made of plastic is additionally installed at the outside of the leg body in the utility model, since the plastic has the features of lower smelting point, convenience for molding, easiness for achieving a simulated effect and the like, the shell can be used for easily making a variety of decorative patterns of the entire sofa leg. Compared with the traditional manner of directly processing the sofa leg into a required shape, the production cost is greatly lowered, and environmental protection is benefited.

FIELD OF THE UTILITY MODEL

The present utility model relates to a sofa leg, in particular to a composite sofa leg, which is convenient to present a variety of shapes.

BACKGROUND OF THE UTILITY MODEL

Sofa materials are varied, such as wooden sofas, cloth sofas, leather sofas or the like. Common sofa legs adopt ordinary shapes, the materials thereof can be the same as or different from those of the sofa bodies. Common sofa legs are mostly wooden, and iron or aluminum sofa legs are also used, but the requirements on this kind of sofa legs are low, and thus there is no need for too much improvement.

However, with the improvement of people's living standards, some users propose higher and higher requirements on the shapes of the sofa legs and hope to use sofa legs provided with a variety of decorative patterns on the surfaces to improve the visual beauty, therefore a variety of sofa legs provided with decorative patterns on the outer surfaces of the leg bodies appear on the market, for example, a variety of patterns are printed or engraved on the surfaces of wooden sofa legs, or iron sofa legs are directly processed to styles with a variety of patterns on the surfaces via mold processing in the production.

The sofa legs with a variety of beautiful patterns improve the aesthetic degrees, tastes and quality of life of the users, but have the following defects: no matter printing or engraving the wooden sofa legs with processed general shapes, or directly designing the metal sofa legs via mold processing, the manufacturing process is time-consuming and labor-wasted, resulting in an increased production cost; and moreover, more wood or metals will be wasted, which not only increases the production cost, but also is not conducive to environmental protection.

SUMMARY OF THE UTILITY MODEL

The purpose of the utility model is to provide a composite sofa leg, which is low in processing cost and is convenient to present a variety of decorative patterns, so as to solve the above problems.

The utility model achieves the above purpose through the following technical solution:

a composite sofa leg includes a leg body, as well as a shell made of plastic, wherein the upper end of the shell is open, the leg body is placed in the shell, and the top of the leg body is flush with or basically flush with the top of the shell. When being connected and installed with a sofa body, the upper end of the leg body is connected with the sofa body, the shell is used as an ornament, and a visual effect required by a user can be easily achieved by injection molding.

Preferably, the shell is a plastic shell, and is preferably an ABS plastic shell formed by ABS plastic via extrusion molding.

The structure of the leg body has multiple selections, specifically:

the leg body can be made of a foam material and fully fills the interior of the shell.

The foam material can select a polyurethane foam material, which has the feature of light weight and can meet the strength demand of load bearing, in a production process, the shell is processed at first, then the foam material is filled in the shell, and the processing of the entire sofa leg is finished after the foam material solidifies.

The leg body can further include a solid supporting column, and the solid supporting column is vertically arranged in the shell. The solid supporting column herein can be made of such materials as wood, metal and the like and plays a supporting function, and since the solid supporting column is covered by the shell, when the solid supporting column is manufactured, the beautiful appearance thereof is not considered, thereby being convenient to manufacture and saving the material. To conveniently locate the solid supporting column in the shell, the space except the solid supporting column in the shell is filled with the foam material. Compared with a leg body structure made of total foam material, the supporting force of this structure is stronger, and thus this structure is firmer after being installed on the sofa body.

The leg body can also include a hollow supporting column, and the hollow supporting column is vertically arranged in the shell. The hollow supporting column herein can have the same function and material as the solid supporting column, and the only difference lies in that the hollow supporting column better saves the material. Similarly, to conveniently locate the hollow supporting column in the shell, the space except the hollow supporting column in the shell and the inner space of the hollow supporting column are filled with the foam material.

The utility model has the following beneficial effects:

the shell made of plastic is additionally installed at the outside of the leg body in the utility model, since the plastic has the features of lower smelting point, convenience for molding, easiness for achieving a simulated effect and the like, the shell can be used for easily making a variety of decorative patterns of the entire sofa leg. Compared with the traditional manner of directly processing the sofa leg into a required shape, the production cost is greatly lowered, and environmental protection is benefited; and the foam material or the supporting column made of a fewer material and the foam material are used as the leg body, thereby being convenient to process and mold, saving materials and having the advantages of light weight and convenience for carrying.
